This invention relates to certain novel improvements in collapsible.boxes'and has for its principal object the provision of. an improvedconstruction of this character which Wlll be highly "efficient in useand economical in manufacture.

Among the salient objects of'tlieinvention is the production of a box ofthis character wherein there is provided a simplecombi nation of partsfor locking thewall portions of the box in distended position andwherein by the removal'of the locking elements the Walls of the box canbe. expeditiously col lapsedto provide a small compact condition of thebox when in collapsed position to'fa cilitate returning ofthe box fromthe consignee to the original shipper- In accordance with one object ofthe inqvention'there is provided an element, here- Fig.3,

inafter'referred to asthe mainlocking element, which serves as aninstrument for locking certain of the wallportions"ofthe box when indistended position and \vhereinthis element inturn is employed to lock*certain other elements "which are employed to lock certain of the wallportions in distended .po-

Other objects will appear hereinafter;

i Theinvention consists in thecombination and arrangement ofpartshereinafter de scribed and claimed. f

The invention will be best understood by reference to the accompanyingdrawings illustrating the preferred tion, and in which I Fig. 1 is aperspective view of the box embodying "the invention illustratingcertain Wall portions thereof in open position, Fig. 2 is a perspectiveview of thebox illustrated in Fig. 1 showingv the box'incollapsedposition, V

Fig. 3 is a top plan view of thebox illustrated in Fig. 1 showing a partofthe cover thereof removed. Figs is a fragmentary sectional detail Viewtaken substantially online 1+4; of

form of construc- 5'is a fragmentary sectional detailed view takensubstantially on 'line 5-5 of Fig.3, Referring more particularly to thedrawings, especially to Fig. l, the bottom wall of the box is indicatedat 10. To this bottom wall are permanently hinged, through the medium ofexterior hinge members 11, side walls 12 and 13. To the side wall 12oppo- The cover 15 is likewise site the hinge connection'l l permanentlyI lug members 18 and 19'. These lug members The end walls 18 and 19include lug wings 20 defining knuckles 21 arranged in aligned relationand adapted to receive removable pintles or lock pins 22 and 23 havinghead portions 24; serving to limit insertionof these lock pins throughthe knuckles 21. The cover 15 is detachably secured to the end walls 17through the medium of interior lug members 25. These lug members 25include leaf members 26 defining knuckles 27 arranged in alignedrelation adapted to receive removable pintles 28. The side wall 13 hasformed therein openings 29 which are adapted for alignment. with theopenings 30 formed in the knuckles 26 of the lug wings 26 when this sidewall 'isdisposed "in distended position wit-hres'pect to the end walls17. These openings29 permit the insertion of the pintles 28 through theopenings 30 of the knuckles when the cover 15 is disposed in distendedrelation with respect to the endwalls. In Fig.

5 it will benoted that corresponding ends 31 r I of the pintles 28areadapted for abutment with the inner wall surfaces of the side wall 12and that opposite corresponding end portions31" are disposed inwardly ofthe heads 31, asillustrated in Fig. 5, are normally disposed in the pathof withdrawal of the pintles 22 and in this position these end portionsserve to prevent upward movement of the pintles 22. we r y detachablycon nected to the-side wall 13 through the medium of a lug member 32including lu wings '33 having" aligned knuckles 34 bore of the pintles23 for reasons hereinafter un- ,derstood. The corresponding end portionsto receive the main locking'pin 35.- To permit insertion of the mainlocking pin 35 through the knuckles of the lug-wings 33 there is" formedin corresponding corners of the end walls 17 aligned openings 35 throughwhich this main locking pin is inserted when portions thereofare'confined in the bores of the knuckles 34. As willlbe noted in Fig; 4the main locking pin 35 is disposed in the path of withdrawal of thelooking pins 533 so as to prevent upward movement oil these lookingpine. It will be likewise noted in Fig. 5 that this looking, pin isdisposed in the path of withdrawal of the locking); [Jim- :58 throughthe openings :li) thereby preventing wsel't-displaeement of thoselooking; pins.

Prorisicm is made for preventing self-displacement of theniain lockingpin tn the Pl'eE-Tlllll; .initanre this main locking pin inehldes an endporlioailli bil meatei'l asat it? to receivi :1. latehplatr ilS wh clrislllY" otally earried by this main pin, at its bl fureated end portionthrough the medinin oi a suitable pivot pin Ell).

The end portion of the main locking pm as, Upl hlbfllll the hitu wtedend "portion thereof. delines a handle port ion in to facilitatewithdrowing of" the inaii'r lorlilng pin from the position illustratedin Fig. l, when the lateh plate is disposei'l in alignedposition withthis pin.

In order to 1n'event nnanthorimwl removal of thin looking pin there isprovided in the main locking; pin at the bifurcated end portionthereojt', inwardly ol? the pivot pin 39 aligned openings all for thereception of a wire shunt: ii! of a seal elk) of any approved type. Ifthis seal is fl'onnd brokenit will indicate that the main loelzin g pinhas been withdrawn by one not authorized to do In collapsing the boxthus ill-air describei, the main loelr 11; pin and the looking pins .12.E23 and 538 are withdrawn from i the knuckles of the inn wingslopermitthe end walls Ill to be il'oldednpon the bottom Wall 10 and to permittlie eide Wall 12 and eover 15 to be tl'olded upon the bottom it).opposite the end walls 1? andnpon the side wall 13 ie'epcx'tively. Inthis collapsed condition of the box it is apparent that a small eompaetparcel is provided greatl :lacilitaling returning of the bozein thecollapsed condition to the shipper. i

The folding of the end .Wall 1? npon the under side oi the bottom 10 ispermitted by reason that in the preferred form of const rnetion thehinge members 16 are disposed with the hinge leaves .16 thereof on theo1:- terior sin-times of these end Walls and bottom wall It ll.

The meeting: edges oithe wall portions making up the box when indistended position are bevelled an at ll to permit a tight line ofjnnetion between the meeting edges of the walls herein mentioned.

By reference to the accompanying drawlogs it will be noted that thereprovided on the Wall surfaces of the Wall portions making up the box oiiposite each of the hinge leaves a reinforcing strip which in arrangedto receive the connecting elements t? which serve to seem-e the himembers of the hinges to their respective n'all portione Oil the Im.

From the tlGlI-Tlltl'llJtlUll herein it. will. be. rmmiiest that lproviiile a simple eoinbinalion and arrm'iecinent of parts 'i'Ll' ell:ively locking the wall portions maliinej up the box in distemledposition and that this simple combination and arrangementoi? partspermits expeditiom collapsing of these wall portions.
